Rootless Containers with runC

Presented by Aleksa Sarai
Thursday 4:35 p.m.–5:20 p.m.
Target audience: Developer


Essentially all popular container runtimes require some form of root privileges in order to create and manage containers. This becomes a problem for certain systems, where administrators are hesitant to install any software, let alone a container runtime -- many of which allow for privileged containers without authentication.

In this talk, Aleksa Sarai will describe recent work done within runC by himself and other maintainers to allow people to use rootless containers with a well-supported container runtime, as well as discussing challenges discovered by this work and kernel work which is being done to alleviate these challenges and bring a new form of containers to users and developers. In addition, he will briefly talk about image formats and the management of images without privileges as well.
